Mine's charred mixed with dark brown, so it's vaping it heavily, but not combusting, though occasionally I do get a questionable taste. I think it burns around the spring of the filter that comes attached; that's where I find the most "burnt" parts.
Occasionally I'll turn on my 2.0 to heat up and it'll start heating for like 25 seconds then just shut off... Even with a fully charged battery. I click it 5 times to start again and it heats up normally... Anyone have any ideas? Is mine just slightly defective? It's not too bothersome just kind...
Did you put anything on the silicone thing covering the heating element? I think that might be where the taste is coming from. The 2 nipples it came with taste terrible as well, but I have an old one from my tvape 1.0 that I'm using instead.
